Incubator sensors can drift over time. Compare against a reference laboratory thermometer; deviations above 0.3 °C are a threshold requiring attention.
For calibration, bring the machine to a stable temperature (e.g. 37.5 °C) and place the reference thermometer close to the sensor position. After waiting 15 minutes, compare the two readings.
INCUVIONLAB machines have a software-based calibration menu; you can enter the deviation value directly. Use our technical service for annual sensor maintenance.
